I work as a firefighter, generally considered not a very geeky job. I imbrace my geeky lifestyle, comic collecting, video games , d&d, flying little spaceships across a table and so forth. I don't try to hide it and talk about it all the time, so much so that I got one of my workmates into it and we play at work during downtime! What I'm trying to say is you shouldn't be embarrassed about your passions, you may be surprised at just how many people out there are supportive. :-)
